I just upgraded my shaw internet which meant I have to install the new shaw router . I really like my asus rtn16 router and I am wondering if it would be better for me to use the shaw router or my asus rtn16 . any thoughts on this?

If shaw allows you to install the modem yourself, call in asap after and request to have bridge mode enabled so you can use your own router. If the tech comes in insist on a modem and not a modem/router combo, if that isnt possible the ask him to enable bridge mode. Their modem router combos are terrible.
